The Leech Bomb was a device. When thrown at an enemy or group of enemies, it created a yellow explosion which sucked Nanotech from enemies within the blast radius and transferred them to Ratchet. Enemies can also be killed by the Leech Bomb, when weak enough. Up to two Leech Bombs could be held at a time. This device functioned similarly to the NanoLeech mod. A better version, the Mega Leech Bomb, could also be purchased.
It cost 1000 bolts per bomb.
